Benefits of technology

The invention is about a medical ultrasonic treatment device that is easier to assemble and reliable. The use of a circuit board simplifies the manufacturing process and reduces assembly time. The contact sections on the circuit board provide efficient electrical power distribution to the piezoelectric elements. The arrangement of the piezoelectric elements and contact sections into a stack results in a simple and reliable assembly. A plastic body simplifies the assembly process and serves as a fastening mechanism for the circuit board. Overall, the invention improves the efficiency and reliability of ultrasonic treatment devices.

Problems solved by technology

The manufacture of such an ultrasonic vibration generator, in particular, the soldering of the metallic wires to the electrodes, is difficult and time-consuming, not least because of the small dimensions of the components, and there is always the risk of an incorrect assembly.

Embodiment Construction

[0068]FIG. 1 shows a medical, particularly dental ultrasonic treatment device 1 for the generation of ultrasonic vibrations and for the transmission of the ultrasonic vibrations to a tool 2. The ultrasonic treatment device 1 comprises a vibration-transmitting hand grip element or handpiece 20 and a medical or dental tool 2, which is in particular operable with vibrations. The handpiece 20 comprises a hollow outer or grip sleeve 23, in which an ultrasonic vibration generator 3 with a plurality of piezoelectric elements 4 is arranged, which will be presented in detail below. The tool 2 is detachably held in a preferably form-fitting tool-holding device 21. An oscillating axle 22 (see for example FIG. 4) connects the tool-holding device 21 to the ultrasonic vibration generator 3, so that tool 2 can be operated by ultrasound.

[0069]A supply hose 24 serves to connect the handpiece 20 to a control and / or supply device 25. During operation, the handpiece 20 and the tool 2 can be supplied th...

Abstract

A medical, particularly a dental or dental surgical, ultrasonic treatment device for generating ultrasonic vibrations and transmitting the ultrasonic vibration to a tool, which can be connected to the ultrasonic treatment device, the medical ultrasonic treatment device having: an ultrasonic vibration generator with a plurality of piezoelectric elements to which an electric voltage can be applied, and a circuit board to supply the plurality of piezoelectric elements with the electric voltage. Furthermore, a method for manufacturing a corresponding medical ultrasonic treatment device is described.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]The present application claims priority from pending European Patent Application No. 17164040.2, filed Mar. 31, 2017, which is incorporated herein by reference.FIELD[0002]The present application relates to a medical, particularly a dental or dental surgical, ultrasonic treatment device for generating ultrasonic vibrations and for transmitting the ultrasonic vibrations to a tool, which is or can be connected to the ultrasonic treatment device. The ultrasonic treatment device preferably includes a dental tartar removing device, frequently called a scaler.DESCRIPTION OF PRIOR ART[0003]Such a medical, particularly dental or dental surgical, ultrasonic treatment device is disclosed, for example, in commonly-owned U.S. Pat. No. 8,314,605. To generate the ultrasonic vibrations, this treatment device comprises an ultrasonic vibration generator with a plurality of piezoelectric elements, particularly piezoceramics, to which an electric voltage can ...
